Canonmp830 have had printer for 1 year and have had no problems, it will not power up at all, have checked wall socket and printer cable and plugged printer into another wall socket,and still no power, power did go off for a while a week ago but no other appliances have been affected, printer is plugged directly into power board with all other pc appliances??

1 Press to turn the printer off. 2 Disconnect the power cord from the wall outlet. 3 Gently remove the power supply from the printer. 4 Reconnect the power supply to the printer. 5 Plug the power cord into the wall outlet. 6 Press to turn the printer on.
Make sure the cord on the back of the printer is pushed all the way into the socket, it should only fit one way. If that fails, check that there is power at the outlet you are using.

1-check the power cable if it is twisted from both sides. or buy new power be sure it is inserted nicely into the printer socke.t
2- check the plug if there is any fuse! if it is blown up., change the fuse with the same amp rate.
3-check power source socket...try another power source wall socket.
4-keep long press on the power on.
I hope will do....otherwise something went wrong with your internal power supply good luck.

First, try pressing and quickly releasing the Power button to start a Power On/Off cycle. Do not hold down the button. If this resolves the problem your done; if not continue on.

Inspect the power cord for visible damage; if damaged will need to contact HP to replace.

Disconnect the power supply (power module and cord) from the power source (wall socket) and the printer.

Test the power source, wall socket with or without your power bar or surge protector in place, with a small appliance you know works to confirm you have power. You may want to test the wall socket first and then test the power bar, etc. to make sure each component is not the problem.

If the appliance works then need to investigate the power supply. If the small appliance does not work you may need to check your electrical panel for a tripped breaker and possibly consult an electrician to check your electrical wiring.

To test the power supply plug in to the working power source; if the green light on the power supply does not light up you will need to contact HP to replace the power supply.

If the green light on the power supply lights up; reconnect to the printer.

Press and quickly release the Power button to turn the printer on. if the printer does not turn on you will need to check the USB cable.

Disconnect the USB cable from the printer.

Press the Power button to turn on the printer; if the printer turns on you will need to replace the USB cable.

If printer does not turn on, check the battery if your printer has one. A red light means the battery requires recharging; if it is still red after recharging, replace the battery.

If none of these steps resolve your issue before replacing the power supply try plugging the power supply directly in to a different working wall socket with no power bar or surge suppressor.; Press the power button.

If still no power to the printer you need to replace the power supply.

Step 1: Reset the printer
CAUTION: Do NOT perform any other type of reset on the printer before the ink initialization process has been completed.
Without turning the power off, remove the power cord from the back of the printer and from the wall socket.
Wait 30 seconds and reconnect the power cord to the printer and to the wall socket. Turn the unit on if it is not already turned on.
Check the printer for the error message. If the error message still displays, go to the next step.

Step 2: Semi full reset
1. Unplug the power cable from printer when the printer is powered on.
2. Press and hold # and 6 while plugging in the power cord.

Step 2: Semi full reset
1. Unplug the power cable from printer when the printer is powered on.
2. Press and hold # and 6 while plugging in the power cord.

1. completely unplug power cord from wall socket,
2. unplug power cord from printer
3. unplug printer cable completely from computer
4. unplug printer cable completely from printer.
5. let printer stay disconnected for approx 1 minute
Now securely:
1. reconnect the printer cable to the printer.
2. reconnect the printer cable to the computer
3. reconnect the power cord to the printer
4. reconnect the power cord to the wall socket

turn printer on

You may find that a connection has simply worked itself loose over time.

Before you actually replace the power supply, check some other things first:
1. Wall socket
2. Power strip/surge protector
3. Power cable
4. On the back of the computer, where the power cable plugs into, is the red switch set to 115? It should be 115.
5. Make sure that the power cable is not connected to a regular extension cord. Power cable must plug directly into a surge protector that is not daisy-chained to another power strip, surge protector, or normal (household) extension cord. Surge protector must be directly plugged into wall socket.

If none of the above solve the problem, open up the case and ensure that all power connections are secure. Also check ALL other components' connections. Any loose connections can cause problems for you.

If everything is secure and the problem persists, replace the power supply.

have u checked the current

Hi. I just got off of the phone with an HP case manager. I was ready for a refund, but he helped me and now my printer is working fine. The key is to have your Officejet 6310 plugged directly into a wall socket. The variations of power through a surge protector often cause a power shortage to the unit. The 6310 needs the 110 volts to operate. Surge protectors will sometimes rob the unit of this power. Follow these steps:
1. Unplug the power cable & ethernet/usb cable from the unit (stand alone mode). Let it sit for a minute.
2. Plug the power cable directly into a wall socket. Then plug the power cable into the 6310.
3. After it powers up, push the "Setup" button.
4. Right arrow to "2.Print Report."
5. Press "OK" button.
6. Right arrow to "4.Self-Test Report."
7. Press "OK" button.
A page should print showing alignment and color settings. Now you're back in business!

hi,
try this
> connect the power chord directly to the wall socket.
> check with different wall sockets.
> unplug and plug in back the power chord. make sure that it is securely plugged in.
> check whether there is a light on the box which comes between the printer and the wall socket.
> if there is light and you hav the problem u need to service the unit else power chord may be the problem.
thanks and regards
